Be it known that I, CHARLES H. ArARs, a citizen of the United States,residing at Salem, in the county of Salem and State of New Jersey, haveinvented certain new and useful Improvements in Can-Feeding Mechanism,of which the following is a specification.

In changing grades of the granular material, or in changing sizes ofcans to be filled, there is danger that the liquid meas uring device maynot be properly adjusted and a surplus of liquid be fed to the cans. Insuch cases some of the granular material may be floated or flushed overthe edge of the can. The objectof my invention is to provide simplemechanism which will effectively prevent such overflow. This object Iattain in the following manner, reference being had to the accompanyingdrawing in which Figure 1 is a view partly in vertical section andpartly in elevation of the feed mechanism of a can filling machineembodying my invention,

Figure 2 a sectional view on line 22 of Figure 1, and

Figure 3 a perspective view of a disk which is a feature of myinvention.

In the drawings the numeral 1 indicates the frame of the machine, 2 thefunnel wheel, 3 the turret, and 4 the hopper. In the form shown thefunnel wheel is splined to a vertical shaft 5 and includes funnels 6 forthe granular material and funnels 7 for the liquid, the liquid funneldischarging into the granular funnel at a point 8 above the necks 9through which both materials pass to the cans 10. The above describedfeatures constitute no part of the present invention.

I provide a disk 11 provided with a series of openings 12 correspondingin number with the number of funnels, and substantially corresponding insize to the exterior of the necks of the funnels, and with a centralopening 18 adapted to receive the shaft. The disk is preferably providedwith upwardly extending annular flanges 13 surrounding the openings andhas a. depending boss 14 bored to receive the shaft. The boss isprovided with an annular groove 15 adapted to receive lugs 16 extendingfrom the parts of a split nut 17 having an interior thread correspondingto a thread 18 on shaft 5. The parts of the nut are connected by bolts19.

In use disk 11 is mounted on shaft 5 with its opening 12 in registerwith the openings in the necks of the funnels. Nut 17 is then screwedupwardly thereby moving the disk upwardly, with the walls of openings 12embracing the necks 9 of the funnels, until its lower surface is at alevel suflicient to permit cans of the size to be used to be readily fedthereunder but not sufiicient to permit any part of the granularcontents of the can to escape. The disk should extend sufficientlybeyond the outer line of openings 12 to cover cans of any diameterlikely to be fed to the machine.

It will be seen that a disk as constructed and positioned willcompletely cover any space between the peripheries of the funnel necksand the peripheries of the cans and will absolutely prevent escape ofany of the granular contents of the cans.

While I have described my invention as taking a particular form, it willbe understood that the various parts may be changed without departingfrom the spirit thereof, and hence I do not limit myself to the preciseconstruction set forth, but consider that I am at liberty to make suchchanges and alterations as fairly come within the scope of the appendedclaims. I

I-Iavingthus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. In a canning machine, a series of feedfunnels having tubular necks; a disk having a series of flanged openingsadapted to embrace the necks, and means for adjusting the diskrelatively to the necks.

2. In a canning machine, a series of feed funnels having tubular necks;a drive shaft; a disk mounted upon the shaft and having flanged openingsadapted to embrace the necks of the funnels; a boss depending from thedisk and embracing the shaft, and a split nut mounted upon a threadedpart of the shaft and engaging with the boss.

3. In a canning machine, a series of feed funnels, a shaft; a diskmounted upon the shaft and having openings adapted to embrace the necksof the funnels; a boss depending from the disk and embracing the shaftand provided with an annular groove; a split nut mounted on a threadedpart of the shaft and lugs projecting from the split 6 nut and takinginto the groove.

4. In a canning machine, a series of feed funnels having tubular necks;means for feeding granular and liquid material to the funnels; a diskhaving a series of flanged l0 openings adapted to embrace the necks ofthe funnels, and means for adjusting the disk upon the necks.

In testimony whereof I have signed my name to this specification in thepresence of tWo subscriblng Witnesses.
